112. The valve stem 113 extends upwardly and is normally positioned against the bottom of the weight 116. The weight 116 iits in the cavity of the casing 112 so that it will act as a piston to push the stem 113 downwardly when air or gas under pressure is introduced into the upper portion of the chamber in the casing 112. The casing 112 is provided with a suitable lid 117 which is threaded or otherwise suitably secured thereon. The lid 117 is provided with a suitable bore 118 in which is threaded an elbow 119. The pipe 72 is operatively threaded on said elbow.

lith the valve 114 open, and the valve 79 closed, the diaphragm 97 holds the rod 102 in the position directly above and in spaced relation to the cap 33 on the rod 32. The lid 12 is also provided with a threaded bore 120 in which is threaded the escape valve 121. rThe escape valve 121 is set to provide a vent which will provide a constant escape of air from the chamber 15. The escape valve 121 is 'fully described in my co-pending application, Serial Number 633,983 and its uses and purposes are fully described in my pending applications Serial Numbers 560,876 and 46,791.

The tank is provided on the bottom wall thereof with a suitable opening 122 in which is threaded an outlet pipe 123. The outlet pipe 123 leads to a bottling machine or to an apparatus for filling bottles with liquid from within the tank 10. It desired, a number ot bottling machines or bottling devices may be operatively connected to the outlet pipe 123 and a high pressure and a low pressure ma chino may be operatively connected to the outlet pipe 123 and operated at the same time by interposing a pressure reducer in the line leading to the low pressure machine.

Tater is iirst introduced into the tank 10 through the pipe 17. Then the machine is iirst started, the float 44 will be in a downward position, thus raising the member 34 and forcing the spring 36 ugwardly against the head 33 and opening the valve 31. rlhe downward position of the float 44 raises the arm 52 and opens the valve 58. The spring 81 holds the valve 79 in a closed position. rihe arm 85 is held in its normal horizontal position by reason of said spring 81. As water is introduced through the pipe 17 into the chamber 34, itflows downwardly through the tubes 23 into the chamber 15 ot the tank 10. As the chamber fills with carbonated liquid, air or gas enters the openings 62 and escapes through the pipe 57 into the pipe 72. The pressure from this escaping air forces the weight 116 downwardly opening` the valve 114. The air thus escaping through the valve 58 escapes outwardly through the openings 134 in the casing 112. The tube 111 is provided on the interior face thereor1 with an annular groove 135 and suitable openings 136 are formed in the wall of the tube so as to communicate with said groove. Approximately the lower half of the stem 113 is grooved to permit air to escape from the lower casing 98 through the grooves 137 which are formed in said stem. The air in the upper portion of the casing 98 escapes outwardly through the opening 136 thereby releasing all pressure on the upper side of the diaphragm 97 and permit-ting the spring 106 to force the diaphragm to its upward position. This permits the valve 31 to be operated freely without hindrance from the rod 102. As the water in the chamber 15 reaches the desired level, the float 44 closes the valve 58 and restricts the flow of water through the pipe 17. This however is not sufcient to entirely stop the flow of water from said pipe. As the water rises the arm 42 contacts with the arm thus raising said arm and forcing the valve 79 downwardly opening the lower end of the pipe 83. The pressure within the chamber flows upwardly through the pipe 83 and creates a pressure in the upper casing 98. T he pressure in the casing of the chamber 98 closes the valve 114 and forces the diaphragm 97 to its downward position, thus forcing the rod 102 downwardly and causes the same to engage the head 33 of the bolt 32, thus entirely closing the upper end of the pipe 17 and discontinuing the flow of water therethrough. As soon as the water within the tank is brought to the desired level, the float 44 will bring the arm out of contact with the arm 85, thus permitting the spring 81 to close the valve 79. It the pressure within the chamber 15 becomes too great to permit the flow of liquid into the chamber 15, the float 44 will open the valve 58 and permit air to escape through the pipe 72 as hereinbefore described.

In ordinary use, the iioat 44 is sufficient to regulate the operation oi' the valve 31 and the apparatus will operate under normal conditions without operating either the valve 79 or the valve 58. Then ordinary apparatus is used the stopping of the bottling machine or any stoppage of the outlet tubes will cause the chamber 15 to lill to a level above the desired height. The apparatus herein described overcomes this objection and is particularly useful when the bottling machine or other apparatus connected to the out-let pipe 123 is stopped.

It will be seen from the foregoing descrip- 1 tion that I have provided a new and improved apparatus which is principally designed to remove free air and other undesirable gases from a liquid heavily charged with carbondioXide gas and that I have provided new and advantageous improvements over the structure shown in my pending applications, Serial Numbers, 560,876, and 46,791.
